An air-filled capacitor is charged, then disconnected from the power supply, and finally connected to a voltmeter. Explain how and why the potential difference changes when a dielectric is inserted between the plates of the capacitor.
(b) The sum of the charges on both plates of a capacitor is zero. What does the capacitor stote?

Because the charges on the plates of a parallel-plate capacitor are opposite in sign, they attract each other. Hence, it would take positive work to increase the plate separation. What type of energy in the system changes due to the external work done in this process?
An air filled capacitor consists of two parallel plates, each with an area of 7.60 cm^2, separated by a distance of 1.80mm. A 20.0V potential difference is applied to these plates. Calculate
(i) the electric field between the plates
(ii) the capacitance and the charge on each plate.
